Patch 1-3 are from Luiz, added Markus's comments, discussion could be found here: http://lists.nongnu.org/archive/html/qemu-devel/2012-07/msg02716.html Patch 3 was changed according Paolo's comments.
Patch 4-5: because qemu_opts_create can not fail while id is null, so create function qemu_opts_create_nofail and use it. Patch 6: create function qemu_opt_set_number, like qemu_opt_set_bool. Patch 7: add def_value and use it in qemu_opts_print. Patch 8: Create functions to pair with QEMUOptionParameter parser. Patch 9: Use QemuOpts parser in Block. Patch 10: Remove QEMUOptionParameter parser related code. Patches 1 - 6 have been merged into block branch, so only patches 8 to 10 are included. v7->v8) 1) print "elements => accept any params" while opts_accepts_any() == true. 2) since def_print_str is the default value if an option isn't set, so rename it to def_value_str. 3) rebase to upstream source tree. 4) add gluster.c, raw-win32.c, and rbd.c. v6->v7: 1) Fix typo: enouth->enough. 2) use osdep.h:stringify(), not redefining new macro. 3) preserve TODO comment. 4) fix typo: BLOCK_OPT_ENCRYPT->BLOCK_OPT_STATIC. 5) initialize disk_type even when opts is NULL. v5->v6: 1) allocate enough space in append_opts_list function. 2) judge if opts == NULL in block layer create functions. 3) use bdrv_create_file(filename, NULL) in qcow_create funtion. 4) made more readable while using qemu_opt_get_number funtion. v4->v5: 1) Rewrite qemu_opts_create_nofail function based on Peter Maydell's comments. 2) Use g_strdup_printf in qemu_opt_set_number. 3) Rewrite qemu_opts_print. 4) .bdrv_create_options returns pointer directly. Fix a bug about "encryption". 5) Check qemu_opt_get_number in raw-posix.c. v3->v4: 1) Rebased to the newest source tree. 2) Remove redundant "#include "block-cache.h" 3) Other small changes. v2->v3: 1) rewrite qemu_opt_set_bool and qemu_opt_set_number according Paolo's coments. 2) split patches to make review easier. v1->v2: 1) add Luiz's patches. 2) create qemu_opt_set_number() and qemu_opts_create_nofail() functions. 3) add QemuOptsList map to drivers. 4) use original opts parser, not creating new ones. 5) fix other bugs.
